  • Mason Banner

    It has taken longer than I had hoped to come to fruition, but the building banner created by the District to honor your school’s Fully Accedited status has finally arrived and is in the process of being hung by Buildings and Grounds, with a completion schedule by no later than Friday, December 20. In addition, the District has purchased 2 city street billboards to recognize Mason’s academic success. Please let your parents and staff members know to look for Mason’s boards scheduled for the following locations:Watson & Southwest (Right Across The Street) and Southwest & Lowry.

  • AIM for Fitness

    Jackie Joyner-Kersee, AIM for Fitness Representative and Spokesperson visited Mason Elementary School on November 14, 2013. She came to promote the AIM for Fitness Project and to highlight the importance of physical activity and nutrition. She helped motivate students to improve and maintain their own personal health and wellness. Mason also had other representatives to help provide parents/guardians with strategies to increase daily levels of physical activity and improve eating habits for themselves and their child/children. Mason students and staff had a wonderful experience meeting Jackie Joyner Kersee and learning more about AIM for Fitness.

  • Mason Makes Full Accreditation

    ST. LOUIS, MO, August 23, 2013- The Missouri Department of Elementary and Secondary Education (DESE) today released the Annual Performance Reports (APR) for districts and individual schools through the Missouri School Improvement Program (MSIP) cycle five. An additional 13 SLPS schools earned enough APR points to qualify for Full Accreditation. Mason has made FULL ACCREDITATION!!! All public school districts and individual schools received an APR score based on Missouri Assessment Program (MAP) tests results. The 2012-2013 school year is the first year DESE has calculated APR scores for districts and schools based on the MSIP cycle five standards. MSIP cycle five uses a 140 point scale to calculate a district’s APR, requiring a district to earn at least 70 points (50%) to qualify for Provisional Accreditation, at least 98 points (70%) to qualify for Full Accreditation and at least 126 points (90%) to qualify for Accreditation with Distinction. Under the MSIP cycle four scoring system, districts were evaluated based on a 14 point scale.

  • Lego League Team

    Mason had our first Lego League competition last Spring and it was a huge success. We are now forming our next Lego League team with our first competition in November. Students will have to do research, presentations, and creations for the competition as well as have their NXT Robot perform given tasks. Students ages 9-14 are able to apply. Students must be able to meet before and/or after school for meetings and travel to other schools for mock competitions. If you are interested, please see Mrs. Palsenberger. The team will be formed by August 30th.
